<p>for that one there's a lot of interesting cases  to cover. e.g. how the trait method can still be chosen over an inherent method, if the inherent one was picked through auto(de)ref</p>

<p>specifics on the migraiton is <em>exactly</em> what is missing :)</p>

<p>I think the section should</p>
<ul>
<li>describe what the automatic rewrite does and when (sometimes you will have to do it manually)</li>
<li>if applicable, describe why you might not want that (e.g., for the closure rewrites, we are forced to be conservative, so maybe you want to undo them)</li>
<li>describe some other options you might want when doing a migration</li>
</ul>
<p>It occurs to me we should also include a section describing how you can turn the lints on with <em>warnings</em>, versus using cargo fix. Some people might prefer to make the edits manually.</p>

<p>We haven't yet decided on a final name for the prelude lint yet, right? I believe I saw desire to change it (which makes sense, I frankly didn't expect the original name to last so long without bikeshedding)</p>

<p>I can probably do this, but I'm not sure what document needs to be updated. Is this referring to the edition guide? The reference? (That <a href="https://github.com/rust-lang/rust/issues/242">#242</a> is pointing to rust-lang/rust, which can't be right :P )</p>
